How hazard and risk differ in workplace safety terminology?

• A. Hazard is punishment; risk is reward
• B. Hazard equals injury, risk equals cost
• C. A hazard is a source of potential harm; risk is the likelihood and severity of harm if exposed.
• D. Hazard is PPE; risk is compliance

Answer: (C)

In workplace safety, you first identify a hazard as anything that could cause harm. That means the hazard is a source of potential injury or damage—like a chemical, a sharp edge, a wet floor, a high-noise area, or a powered machine. Risk, on the other hand, looks at what happens if exposure to that hazard occurs. It combines how likely harm is to happen and how serious that harm would be. Exposure factors—how often someone is near the hazard, for how long, and under what conditions—shape the level of risk. If you can reduce exposure or the severity of harm, you lower the risk. For example, a hot surface is a hazard. The risk depends on how likely someone is to touch it and how badly they could be burned, which can be diminished by guarding, using proper PPE, or providing clear procedures. The other statements mix up these ideas, treating hazards as injuries or costs, or equating PPE or compliance with risk. The correct concept keeps hazard as the potential source of harm and risk as the likelihood and severity of harm given exposure.
